2 OpenBAN - Signal Acquisition Device

Figure 2: OpenBAN.

The OpenBAN is the single channel device of the biosignalsplux Solo kit that collects and digitizes all signals from a single biosignal sensor and transmits them via Bluetooth to the computer, where they are recorded and visualized in real-time. The OpenBAN supports sampling resolutions of up to 16-bit and 1000Hz sampling frequency. OpenBAN is compatible with most available biosignalsplux sensors, although the usage of some sensors is restricted due to the limited amount of sensor inputs (see chapter 3 Sensors for more detailed information about this topic). Additionally, the OpenBAN has integrated sensors such as an triaxial accelerometer, triaxial magnetometer and a microphone.

2.2 Ports and Peripheries

Figure 3: OpenBAN ports, LED, microphone placement & on/off switch.

2.2.1 On/Off Switch – Turning the Device On and Off

In order for the device to work, it must be turned on. Turning on the device can be done by sliding the on/off switch which is placed at the right side of the device into the on position (I-position). After being turned on, the LED status light will blink once per second (green). Sliding the switch into the off-position (O-position) will turn off the device.

2.2.2 Sensor Port – Connecting and Disconnecting Sensors

WARNING Do not use damaged sensors, devices or components, as this can cause serious injuries and device damages. Contact PLUX’s Technical Assistance to report such issues and report malfunctioning devices or sensors without hesitation.

The OpenBAN has only a single sensor port where biosignalsplux sensors can be connected to the device. Do not try to connect the sensor into the micro USB charging port as this might damage the equipment and harm the user. Also, when connecting the sensors, pay attention to where the cables go to avoid device damages or disrupting the user’s movements.


10 of 75

Disconnect the sensors according to the recommendations displayed below, to avoid damaging the biosignalsplux device or the sensors:

• don’t twist the sensor while disconnecting

• don’t apply upward force or pull the cable

• use minimal force to disconnect

• hold the plug firmly and pull it out

• don’t pull the cable

2.2.3 Micro USB Charging Port & Charging LED – How to Charge the OpenBAN

WARNING Do not use the OpenBAN device during the charging process.

NOTE Follow the indications on how to correctly charge your device to prevent any damage of your system or of the OpenBAN user(s).

OpenBAN has a battery lifetime of up to 16 hours in continuous usage. Note, that the lifetime might vary depending on the number of active sensors (incl. built-in sensors). The built-in LED will light up red if the battery is running low until the device stops working. To recharge, turn off your OpenBAN by sliding the on/off switch into O-position (see Figure 3) and use the micro USB cable which comes with your kit by connecting the USB-A connector to an USB port of your computer and the micro USB connector to the micro USB charging port of your OpenBAN (see Figure 3). The charging process will take approximately 2 ½ hours to fully charge the battery.


11 of 75

WARNING Make sure your device is turned off in order to charge it. If the device is turned on during the charging process, the charging LED will turn red and the device will not be charged. If the charging process is being done correctly, the charging LED will turn purple. If the charging LED turns red during the charging process, even when the device is turned off, disconnect the micro USB cable from your OpenBAN and contact PLUX’s Technical Assistance.

The suitable room temperature when charging the device must be between 10°C and 35°C to prevent device or user related damages during the charging process.

WARNING Unplug the charger from your computer if the battery/device overheats (reaching 60°C) and immediately get in contact with PLUX’s Technical Assistance.

2.3 Status LED The status LED at the centre of the OpenBAN provides basic visual information about the current device state (e.g., green blinking with 1Hz frequency device is in idle mode, green blinking with 2Hz frequency device is streaming data). Please check the OpenBAN’s datasheet for more detailed information about the status LED and the device states.

2.4 Microphone The microphone allows you to record sound during acquisitions. Make sure the microphone is not covered during acquisition to be able to record any useful audio data.

2.5 Communication The communication with OpenBAN devices is done via Bluetooth Class II only. Bluetooth is used to configure the device, to acquire and transmit sensor signals in real-time to the computer and upload new firmware versions to your device. Since most internal Bluetooth modules are not designed to support high transfer rates as those are needed when acquiring and streaming signals using OpenBAN, we strongly recommend using the PLUX Bluetooth dongle (which comes with your biosignalsplux Solo kit) to prevent any communication issues or connection losses. These dongles have been tested and verified by PLUX to work properly with any biosignalsplux device.





12 of 75

The Bluetooth dongle can be found in our store if several dongles are needed (e.g. to use biosignalsplux Solo on several computers without having to change the Bluetooth dongle every time another computer is being used1). https://store.plux.info/biosignalsplux-accessories/368-bitalino-proven-bluetooth-dongle-820201511.html Instructions on how to connect the OpenBAN device via Bluetooth to the computer can be found in the 4 Bluetooth Setup section. If you’re experiencing a great number of connection loss events, reconnection problems, missing samples or similar problems, your internal Bluetooth module might be being used for data transmission or your Bluetooth dongle might be configured to use the wrong Bluetooth stack. Instructions to set up the correct Bluetooth stack and to solve such problems can be found in the 6.1 Bluetooth section of this manual See the table on the following page for detailed Bluetooth specifications of the internal Bluetooth module of biosignalsplux devices (incl.

3.2.8 Light (LUX)

A common need when working with biosignals is the synchronization of the recorded data with external sources (e.g. a computer screen for visual evoked potentials). If applied to the computer screen, our LUX sensor can be used to detect chromatic changes in the stimuli, hence providing a synchronization source. The LUX sensor can also be useful for optical synchronization with third-party devices (provided that the third-party device can trigger an LED), in applications where it is important to have electrical decoupling between devices.

Figure 26: Light sensor.

How to configure your sensor in OpenSignals (r)evolution Note, that the signal you are acquiring with this light sensor is affected by the ambient light and other light sources that are available at your experiment setup. Therefore, it is needed to adjust the acquired signal to fit to your application and setup. For this, open the OpenSignals (r)evolution device manager and select the device you have your light sensor connected to. Select the channel of your light sensor and select CUSTOM from the dropdown menu (click on the arrow in the channel’s field that appears when you hover over the channel’s field). In the custom field of your channel, adjust the GAIN and OFFSET that fits best to your application. Testing and readjustments of this parameters might be needed to find the configuration that fits best your needs.

3.3.5 Blood Volume Pulse (BVP)

This Blood Volume Pulse (BVP) sensor is an optical, non-invasive sensor that measures cardiovascular dynamics by detecting changes in the arterial translucency. When the heart pumps blood the arteries become more opaque, allowing less light to pass from the emitter on the sensor through to the receiver. The BVP sensor has a plastic clip-on housing for placement on the finger, which houses the light emitter and detector, and also minimizes interferences from external light sources.

6 Troubleshooting

6.1 Bluetooth Most internal Bluetooth adapters are compatible with PLUX devices. However, if you’re experiencing a great number of connection loss events, reconnection problems, missing samples or similar problems, your internal Bluetooth module might not have enough performance to deal with the data throughput of the device you are using. In this case, reducing the sampling frequency or the sample resolution might solve this issue, if a change of these parameters is possible. For this reason, PLUX has identified Bluetooth dongles that have been tested and are known to work with our devices. We recommend that you use one of these PLUX-tested Bluetooth dongles, which are either already shipped with your device (e.g. in the case of biosignalsplux kits) or can be purchased separately from our store. These dongles are compatible to work with data rates up to 24 Mbps. The solution is to exchange the internal Bluetooth Adapter for an external Bluetooth USB dongle that uses the Windows native Bluetooth stack. For this, you’ll need to install the Bluetooth dongle properly, as described in the following steps, which are explained in more detail throughout the next pages for the supported operating systems: Step 1: Removing already paired devices from your operating system Step 2: Installing PLUX-proven Bluetooth dongle Step 3: Changing Bluetooth Stack to Microsoft’s native Bluetooth stack NOTE If you’re already using PLUX devices with the old Bluetooth stack, please remove your device(s) from your computer before changing the Bluetooth drivers/changing to Microsoft Bluetooth Stack.

NOTE We recommend going through all the following steps to set up your Bluetooth dongle correctly, even if Windows may automatically install and set up your dongle.

NOTE Installing the Bluetooth dongle and changing the Bluetooth stack is only required for Windows computers only. Computers with a Mac OS X operating system do not need to go through these steps and use the internal Bluetooth adapter instead.


59 of 75

6.1.1 Windows 7 & Windows 8

Step 1: Removing already paired devices from your operating system To remove Bluetooth devices, it is needed to access the Device Manager on your computer and view the list of connected devices. The device list can be found following these steps: Start Button > Control Panel > Hardware and Sound > View devices and printers In the Device and Printers window, PLUX devices can be found in the Unspecified section. Right-click on the device you want to remove and select Remove device (see Figure 63)

Figure 63: Windows 7 "Devices and Printers" window.

If the device is not listed under Unspecified anymore, it has been successfully removed from your system. Step 2: Installing PLUX-proven Bluetooth dongle To install the PLUX-proven Bluetooth dongle, plug it in and install all the necessary drivers for the Bluetooth dongle to work (an Internet connection is advisable). Windows should display the window below.

Figure 64: Wait for Windows to install your Bluetooth dongle.

Make sure you wait until your Bluetooth Dongle is installed. Windows will issue a notification and you’ll be ready to configure the correct Bluetooth stack following the next step. Step 3: Changing Bluetooth Stack to Microsoft’s native Bluetooth stack To configure the Bluetooth stack of the Bluetooth dongle, you have to connect your Bluetooth dongle to your computer and access the Device Manager on your computer. The device manager can be found following these steps: Start Button > Control Panel > System and Maintenance > Device Manager In the device manager, the Bluetooth dongle should be listed as Generic Bluetooth Adapter (see Figure 65). If your machine already has an internal Bluetooth Adapter and you have just plugged in the PLUX-proven Bluetooth Dongle, keep in mind that the last one will be automatically disabled by Windows. This is why one of your Bluetooth adapters under Bluetooth in the device manager shows a yellow warning icon ( ) stating: Code 10 - This device cannot start.

Figure 65: Bluetooth dongle listed in the device manager.

If your Bluetooth dongle is the one disabled, you can manually disable your internal Bluetooth adapter by right-clicking on it in the device manager and selecting Disable. This action will enable your Bluetooth dongle by default. If, after this action, your Bluetooth Dongle continues to display a yellow warning icon ( ) , it means that it is not installed correctly and you should try to update the drivers by right-clicking on it and selecting Update Driver Software... or fix the problem displayed under Device Status in the device properties (right-click the Bluetooth device and select Properties; see screenshot below).
